Re: Pointer question...last for the day? :-)

What will happen if it is a integer pointer or an integer array


void foo(char *s,int *x){

int *f=x;
char *k=s;
*f=6;
*k='a';
}


int main(){

int a[5]={1,2,3,4,5};
char *s="hello world";
foo(s,a);
printf("%s %d",s,a[0]);

return 0;
}

output is "hello world  6"

in case of integer the value changed in the function is reflected in
the callee function but in case of characters it is not the case

Why ???
